摘　　要：目的监测评估2015—2017年烟台市城市饮用水源地水环境健康风险。方法 2015—2017年,对烟台全市17个市政水厂水源水监测点开展监测,监测频率为每季度1次,共检测204份水样。采用Excel 2007建立数据库,使用SPSS 17.0进行统计学分析,运用环境健康风险评价模型计算总健康风险。结果烟台地区饮用水源地水体总体合格率为86.71%,健康风险由大到小的顺序依次为氟化物>硝酸盐>锰>铁>锌>氨氮>(铜、铅、汞、硒)。成人和儿童的总健康危害风险分别为23.78×10^-6/年、32.43×10^-6/年,均为非致癌物质所致。结论烟台市政水源水中健康风险儿童高于成人,均为非致癌物质所致,硝酸盐和氨氮为主要的超标物质,氟化物所造成的平均个人健康风险较高。Objective To monitor and evaluate the environmental health risks of urban drinking water supply sources in Yantai city from 2015 to 2017.Methods From 2015 to 2017,source water monitoring stations of 17 municipal waterworks in Yantai city were monitored.The monitoring frequency was once per quarter,and a total of 204 water samples were detected.Excel 2007 was used for establishing a database,SPSS 17.0 software for statistical analysis,and the environmental health risk assessment model for calculating the total health risk.Results The overall qualified rate of water from the sources of drinking water supply in Yantai was 86.71%.The health risks in descending order were as follows:fluoride,nitrate,manganese,iron,zinc,ammonia-nitrogen(copper,lead,mercury and selenium).The total health risks for adults and children were 23.78×10^-6/year and 32.43×10^-6/year,respectively,which were caused by non-carcinogenic substances.Conclusions The health risks induced by source water of the municipal waterworks in Yantai city are higher in children than in adults,and all the risks are caused by non-carcinogenic substances.Nitrate and ammonia nitrogen are the main over-standard substances,and the average personal health risk caused by fluoride is high.
